FS 301. The Human Overpopulation Crisis

Why are humans in such a state of total denial ("temporal blindness") about what we are doing to this planet?

People are becoming aware of some of the many consequences of overpopulation, but most still refuse to recognize the underlying causes: an economic system based on perpetual growth, and too many people. Just as the pharmaceutical industry targets symptomatic relief for man-made ailments rather than addressing underlying root causes, widespread attention to the many spin offs from growthmania and overpopulation diverts attention away from the real problem.

Exponential population growth is threatening to destroy Spaceship Earth (perhaps a "Lifeboat" is a better metaphor) and its life support systems (see also Can humans share spaceship earth?). This course examines the human crowding dilemma from a wide diversity of perspectives, primarily from a scientific point of view, but we will also briefly consider the impact of religious mythology. First, we will recognize and study the path to ruin we are presently on (see also Kaplan "The Coming Anarchy"). Then, after developing a thorough understanding of natural selection and population biology, we will critically evaluate the multitudinous side effects (symptoms) of overpopulation.

Finally, we will ask what, if anything, can be done to mitigate the mess we have made. We will stop denying what can happen and confront reality head on. We will examine possible future scenarios, including prospects for colonization of space, the inevitable collapse of civilization (anarcho- primitivism), and, ultimately, our return to a hunter-gatherer mode of existence, if indeed, humans don't go extinct.

Supplemental Reading


A knowledge of High School algebra and geometry is assumed. You will be expected to be able to understand 3-dimensional graphs and be able to interpret and manipulate simple equations. You will be expected to learn basic ecology and evolution that everyone should know. You will also be encouraged to think.

This class has a substantial writing component. After thoroughly researching background material, you will write a polished original synthetic essay on some aspect of the human population dilemma (
some suggested possible topics/themes). After your name is removed, your paper will be read and evaluated by the entire class. You will read and evaluate papers by all other students as well. Your grade will be based on your performance in class discussions, exams, and your paper(s).
